Georgia Tech team develops high-performance intermediate-temperature sold-oxide fuel cell

Green Car Congress

A team from Georgia Tech, with colleagues at the university of Kansas, has designed a high-performance solid-oxide fuel cell that operates directly on nearly dry (only ~3.5 Our cell could make for a straightforward, robust overall system that uses cheap stainless steel to make interconnectors. Very few people have even tried it.

A DIY E-bike Conversion on the Cheap

Cars That Think

The handlebar-mounted controls connect with an Arduino, which interprets their settings and translates them into a PPM signal, which is applied to the electronic speed controller. The speed controller is connected to the motor and battery in the usual fashion, with an automotive-type blade fuse in line for safety.

IBM Research discovers new class of industrial polymers; cheaper, lighter, stronger and recyclable thermosets for aerospace, automotive and others

Green Car Congress

Zhang/Virginia Tech. Polymers are long chains of molecules connected through chemical bonds. In a perspective on the IBM paper, also published in Science , Dr. Tim Long from Virginia Tech noted that: Thermoplastics are polymers that become pliable or moldable at elevated temperatures, but return to a solid state when cooled.

Amazon Vies for Nuclear-Powered Data Center

Cars That Think

When Amazon Web Services paid US $650 million in March for another data center to add to its armada, the tech giant thought it was buying a steady supply of nuclear energy to power it, too. A data center could just connect to the grid and draw from the same supply as everyone else, Clark says.

Budget Drones in Ukraine Are Redefining Warfare

Cars That Think

The war between Russia and Ukraine is making a lot of high-tech military systems look like so many gold-plated irrelevancies. That’s why both sides are relying increasingly on low-tech alternatives–dumb artillery shells instead of pricey missiles, and drones instead of fighter aircraft. That’s not cheap, except by U.S.
